A port of the wonderful Tufte CSS framework to logseq.

Based on the layouts & typography of Edward's Tufte's influential books on displaying quantitative data. This approach focuses on careful use of spacing and font weight & style for communicating a hierarchy of information rather than colors or graphical delimiters.

Included is the beautiful et-book serif typeface from tufte-css which is used by default. There are non-technical reasons not to use Tufte's preferred sans serif, but by default this theme doesn't use sans at all. There is a reasonable set of sans fonts set to the --sans var if you want to switch. Monospace will be set in the wonderful Cartograph CF if you have it installed, otherwise MonoLisa or Fira Code or something farther down the stack.

I kept as much of the CSS as seemed reasonable, but removed the styles for margin- and side- notes. They don't fit extremely well with logseq's display model, and wouldn't provide much or any benefit. I also removed the (rather nice) link underline alternative, because it is complex and electron's default underline clears descenders, so the main benefit is unnecessary.
